Which outcome occurs after a criticality accident involving Uranium-235?

💡 Explanation

Neutron activation foils overheat because radiative capture drives a positive feedback loop; the increased neutron flux accelerates fission, therefore the foils melt rather than control rod absorption, because fission releases neutrons.
